Recent advances in the pyrolysis processes and catalysts of waste tires, including the reaction of conditions (temperature, pressure, carrier gas and particle size), catalysts and reactors were discussed and summarized. The operating conditions and the type of reactors directly influence the distribution of pyrolysis products, however, due to the balance between thermodynamics and kinetics as well as heat transfer, mass transfer consideration, it is difficult to obtain desired products only by tuning the operating conditions. Fabrication of the structure and composition of catalysts offers an effective way to improve the yield and quality of target products, promoting high value-added products (monocylic aromatics, cyclohexane and etc.), reducing sulfur in the pyrolytic oil. The problem of separation and coking of catalysts hinders the progress of waste tires pyrolysis, and most of current research were operated in micro or small-scale reactors, therefore deep exploration of the reaction mechanism and molecular structure of waste tires still need to be studied in detail. The design and fabrication of efficient, sulfur-resistant catalysts and large scale pyrolysis reactor were proposed to be the main subject of future research.
